Information obtained from Jones led investigators to also search the Arkansas River and bottoms north of Lavaca Thursday.

Jones is being held in the Sebastian County Detention Center on an aggravated assault charge related to Allen's case.

Allen has been missing since Feb. 10. That night around 7:30 p.m., Allen told her grandmother she was going for a walk in her Van Buren neighborhood and never returned, according to police. Investigators believe Allen and Jones met on a social media site and arranged a meeting. The two had been communicating via text messages for several days, says Crawford County Sheriff Ron Brown.

Several agencies, including the Van Buren Police Department, Crawford County and Sebastian County Sheriff's Offices, Arkansas State Police, the Fort Smith Police Cyber Crimes Unit, and the Federal Bureau of Investigation assisted in the investigation.
